I was barely awake when Bergman called me. It was just a few minutes after the explosion. He told me what was going on and wanted to know whether they could do a direct abort from their current location or would they have to fly by the moon. https://twitter.com/chasingmoonbk/status/1249716715585445888

I asked him how far out the spacecraft was from the earth. Once I knew the distance from earth, I knew they would have to do a fly by. Doing a direct return from their current position would require too much fuel & the return trajectory would still have a very long trip time.
